Description
Great Wyrm Theodorix is a Great Enemy Boss in Elden Ring. Theodorix was once a troll, but was transformed into a magma wyrm through Dragon Communion and now lives on the frozen river in the Consecrated SnowfieldGrace. This is an optional boss, as players don't need to defeat it in order to advance in Elden Ring.

Consider opening the Cave of the ForlornGrace with a Stonesword Key to get a closer Site of Grace, but beware of the Giant Land Octopus guarding its entrance. [Map Link]

Additional Fight Strategy
Goad the nearby Giant Land Octopuses into fighting Theodorix. They can take and deal a lot of damage before going down.
Run past him and climb on the ledge that goes behind his resting spot for a safe zone to snipe him from. This ledge also has an Ancient Dragon Smithing Stone.
